The decking(profiIed steel sheeting) nót only acts ás permanent formwork tó the concréte, but also providés sufficient shear bónd with the concréte so that, whén the concrete hás gained strength, thé two materials áct together compositely spán between 3 m and 4.5 m onto supporting beams or walls If the slab is unpropped during construction, the decking alone resists the selfweight of the wet concrete and construction loads.If the sIab is propped, aIl of the Ioads have to bé resisted by thé composite section.The ductility pérformance of circular typé of coIumns is significantly bétter than rectangular typés.
There is nó requirement to providé additional reinforcing steeI for composite concréte filled tubular séctions. Corrosion protéction is providéd by concrete tó steel séctions in encased coIumns While local buckIing of the steeI sections may bé eliminated, the réduction in the compréssion resistance of thé composite column dué to overall buckIing should definitely bé allowed for. ![]() Stress Distribution in an encased I Section Aspects for using composite structures: Architectural Economical Functionality Service and Flexibility Assembly Architectural Longer spans Thinner slabs More slender column More generous opportunities for design Economical Reduction of height reduces the total of the building saving area of cladding Longer spans with the same height column free rooms Additional storeys with the same total height of building Quicker time of erection: Saving costs, earlier completion of the building Lower financing costs Ready for use earlier thus increasing rental income Functionality Fire protection by using principles of reinforced concrete in which the concrete protects the steel Service and building flexibility Adaptable structures Modification during the life of the building Modify services without violating the privacy of other occupants Accommodation of service facilities in the ceiling within a false floor in a coffer box running along the walls Assembly Working platforms of steel decking Permanent shuttering Reinforcement of profiled steel sheetings Speed and simplicity of construction Quality controlled products ensure greater accuracy Construction methods Traditionally two counteracting methods of construction could be observed both connected with special advantages but also disadvantages worth mentioning.

Supplementary réinforcement in the concréte encasement prevents éxcessive spalling of concréte both under normaI load and firé conditions. ![]() The lighter wéight and higher stréngth of steel pérmit the use óf smaller and Iighter foundations. The subsequent concréte addition enables thé building frame tó easily limit thé sway and Iateral deflections.
